My invention relates to improvements in wall construction materialswhich. are particularly directed to hollow wall, construction and to theprovision of means whereby the various vertical structures of the wallare laterally bonded together by tie blocks which extend from one wallblock to another for the purpose of providing a means wherein continuouslongitudinal reinfo w:e nent may be built into the wall and for thepurpose of forming a wall of great strength and light ness of weight. VThe invention consists essentially of a plurality of blocks having oneor more of their side edges constructed to interlock with other blocksprovided with side edges correspond ing in shape thereto, as will bemore fully described in the following specification, in which: p V

Fig. 1 is a perspective view showing a section of wall constructedaccording to the in-' vention.

Fig. 2 is a perspective view of a section of wall construction showingan external angle.

Fig. 3 is a perspective view of an interior stretcher block.

Fig. tis a perspective view of an interior tie block. r

' Fig. 5 is a perspective view of a face stretcher block.

Fig. 6 is a filler block. r

Fig. 7 is a modified form of block section.

In the drawings like characters of reference indicate correspondingparts in each figure.

The numeral 1 indicates generally a stretcher block, see Figure 3, suchas would be used in the interior of a wall corresponding to a threehorizontal course wall of regular construction, the block is preferablyformed with a longitudinal groove or frog 2 in its upper and lowerfaces, either ofwhich may be effectively utilized for the purpose ofhousing a reinforcing rod 3 which would be embedded in mortar or cementto form a bond longitudinally of the courses where deemed expedient,such as over door and window openings and the like. The side faces ofthe block are formed with vertical portions 4 and 5 which are separatedby an interlocking mould 6 consisting of a tongue 7 and a groove 8. I

The face stretcher blocks see Figure 5, are indicated by the numeral9,which blocks are provided with one moulded side face similar perspectiveview of an end to those. on the interior stretcher blocks l, the otherface be ng afplain vertical surface lllsuitable forfeither exteriorfacing of a bu ldi-ji'ig or forplastering or interior facing;

,ne stretchers 'lyand 9 are laid longitudi' n'allyflof the avail and arespaced apart as shown in Figuresl and 2,'the different divisions of.stretchers being connected together by blocks 1 1, which tie 'blocks areprovided with moulded faces 12 corresponding to those of the blocks 1and 9, so that the tongues, and grooves of the tie blocks will interlockwith the 'sin' ilai parts of the stretchers 1 and 9, with the resultthat a hollow wall is formed wherein the stretchers l and 9. are bondedtogether through face contact by the tie blocks 11. If great strength isnot required in the walls, the tie blocks 11 need only be applied toalternate courses, thus savingv a considerable amount "ofbluildingmaterial. Where a face stretcher block 9 is brought to the, end of awall or to an outside angle of intersecting walls, such is shown inFigure '2, a filler block '13, 'wh eh is provided with a, plain verticalface 14 and a tongued and grooved face 15 but which has a total widthequal to one half only of the tie blocks, is provided, so that thecoi'nbined end face of a face stretcher 9 and a fillerl3 will form arectangle having an inner vertical face against which the end of afurther face stretcher 9 may abut neatly at 16, see Figure 2.

A modified form of block is indicated by the numeral 17, see igure 7 inwhich an interlocking tongue and groove mould 18 is provided adjacentthe upper face of the block. Such blocks would preferably be used inwalls serving as partitions or curtain walls such as would not berequired to support heavy. floors or other loads, and would form a blockwhich would be convenient to handle and tend towards rapid andeconomical. wall construction. The heightof the blocks 17 wouldpreferably be a multiple of the height of a standard brick and itsmortar joints, so that .the laying of one such block would be theequivalent of two or more standard bricks according to the multipleeniiployed. I

i It will be apparent from the foregoing description that the tie blocks11 may be set in any desired posit-ion between the stretcher blocks 1 or9, so that close bonding of the latter may beprovided, or that largevertical cavities may be formed for the endoblocks,

sure of soil stacks, heating pipes and the like and that the stretchercourses may be extended into other stretcher courses at wallintersections to bond the corners and also that effective lateralbonding between adjacent courses may be provided intermediate.

the length of some of the stretchers forming said courses without theneed of cutting or the use of headers.

' lVhatI claim as my invention is:

1. A wall construction comprising spaced courses or superin'iposed' loadsustain ng with the blocks of each course arranged in end to endrelation, the base portion of each block being extended inwardly andupwardly to provide a hooked ledge and a plurality of relatively spacedtie blocks inserted" between said courses each tie block being, iorrnedwith integral extensions adapted to interlock with the hooked ledges ofthe load sustaining blocks of said courses.

2. A wall construction comprising outer and intermediate courses ofloadsustaining blocks, the blocks of each course being arranged insuperimposed rows and in end to end relation, the base portion of eachblock of the outer courses being extended inwardly and upwardly toprovide an integral hooked ledge and the base portion of each block ofthe intermediate course being extended outwardly and upwardly at eachside of the block'to provide hook ledges correspondto the hooked ledgesof the blocks oi? the outer courses and a plurality of relatively spacedtiebloeks arranged between the outer and intermediate courses of theload sustaining-blocks, each tie block being provided at opposite sideswith integral downwardly facing hooked portions adapted to interlockwith the hooked edges of the load sustaining blocks.
